Figure 1.
Benign and unhealthy adipose tissue. The overall health of adipose tissue can be visualized histologically. Benign murine subcutaneous adipose tissue (left; trichrome staining) is rich in unilocular white adipocytes with sparse ECM. On high-fat feeding (right), adipose tissue experiences hypoxia and inflammation, resulting in a dense, fibrous ECM. These histological tissue features are characteristic of insulin-resistant adipocytes.
